As an aside, I'm not sure Pfizer is one of the deal favoutites here, they're surely committed to ADC's :

Pfizer Invests $43 Billion to Battle Cancer - Monday, March 13, 2023
"“Pfizer is deploying its financial resources to advance the battle against cancer, a leading cause of death worldwide with a significant impact on public health,” said Dr. Albert Bourla, Pfizer Chairman and Chief Executive Officer. “Together, Pfizer and Seagen seek to accelerate the next generation of cancer breakthroughs and bring new solutions to patients by combining the power of Seagen’s antibody-drug conjugate (ADC) technology with the scale and strength of Pfizer’s capabilities and expertise."

It would seem 'more than $10 billion in risk-adjusted revenues in 2030' will now be optimistic if pre|CISION trial results and a subsequent launch continues to schedule.
FWIW Myles McNulty had this to say (references not available) last year about ADC's:
ADCs are significantly more targeted, and have a higher efficacy, than conventional chemotherapies.
However, the class of therapy nevertheless comes with several major challenges:
- Unavoidable side effects
Severe side effects (grade 3 or higher) are common with ADCs. The most notable are:
i) blood toxicity, including neutropenia, thrombocytopenia, leukopenia, and anaemia;
ii) hepatotoxicity (i.e. chemical-driven liver damage);
iii) gastrointestinal reaction (including nausea, vomiting, diarrhoea, abdominal cramps).
These three types of side effect are all believed to be related to premature release of cytotoxic payloads
in the blood circulation.
iv) nephrotoxicity (i.e. toxicity in the kidneys). This can be caused by the immune response
induced by the antibody component of the ADC.
v) interstitial lung disease (‘ILD’). Whilst it remains unclear, it has been speculated that ILD
might be associated with the uptake of the ADC in healthy lung cells, and the subsequent
payload release from the ADC. [The lungs enjoy abundant blood flow and long retention –
more so than other organs – and as such, are more under threat from undesirable uptake of
ADCs.]
